Hydro-modifications matter: Influence of vale transformation on microinvertebrate communities (Rotifera, Cladocera, and Copepoda) of upland rivers

Anthropogenic transformations of the catchment area and river bed are responsible for the changes in the geomorphology of the river valleys, the hydrological regime of rivers, the river continuum, as well as the river ecosystems. Transformed valleys offer ecological niches that are different from th...
